Hearing this question, Jing Jiu thought of the scenes on Longevity Mountain and by the Heavenly Well.
It was at the time that the fairy book shone brightly in the Immortal Bai's hands.
Countless rays of the sunlight, summoned by the fairy book, came down from the outside world, the source of which was the sun.
In the next moment, Jing Jiu thought of another scene in the cold and dark world, where a white and blazing fireball hovered quietly while gazing at this world.
The reason the Immortal Bai raised this question was because she had been to that world.
"In fact, I don't need your answer," the Immortal Bai said to Jing Jiu. "There is a fairy veil on Cloud-Dream Mountain, behind which I can see the other world. I've seen that blazing fireball many times since a young age, so I know that the sun in this world is not real, or in other words, it's merely a projection of that sun."
Jing Jiu looked up at the spring sun in the sky, saying nothing.
